2. 1. You need to water as a fuel which is cheaper, easier, and fuelonline. 2. Do not result in air pollution from smoke and pollution of the environment (clean energy). 3. Daily operating costs are cheap. 4. Need less time at the beginning of operation.

3.  1. Different amount of electric power from time to time.  2. High initial costs of building the station.  3. Difficult to perform maintenance

4.  Electricity production  The dam powers twelve generators  each rated at 175 megawatts,  with a total of 2.1 gigawatts.  Power generation began in 1967.  When the dam first reached peak output it produced around half of Egypt's entire electricity production

7.  Worldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power.  Hydropower is the second source of electricity in France.  In France it is 12% of the total electricity production, with an average production capacity of 70 TWh per year

8.  Hydropower plants are based on a rather simple concept  Hydropower plants harness water's energy and use simple mechanics to convert that energy into electricity.  Water flowing through a dam turns a turbine which turns a generator
